The motor only has about 100 hours and is in perfect condition so I am not going to re-power. With this in mind can you tell me what kind of performance I can expect from this combination? I realize it won't be a speed demon, but would like an idea. Will it plane ok? Can I expect 20-25 MPH? Thanks in advance for your response. Wally

After converting to a Montauk interior I had a WOT speed of 26 mph. With 10 more HP I assume you could reach 30 mph depending on your interior layout and load.
